PHOTOGRAPHIC BUTTON.

'Application led Hatch 30, 1927. Serial No. 179,465.

This invention relates to photographic devices. v l

The general object of this invention is to provide a photographic button or medallion having `novel features of construction.

Another object of this invention is to provide an improved photographic button havl ing a fluid tight joint at ythe juncture of the sensitized photoglaphic sheet and the button frame.

Still another object of the invention is to provide an improved photographic button so constructed as to provide a smooth flat back surface. i

Other' objects and advantages of this invention will be apparent from the following description taken in connection with the accompanying drawing wherein:

Fig. 1 is a front view. of my improved photographic button showing the same developed and as having an image thereon.

Fig. 2 is a side elevation of my improved photographic button.

Fig. 3 is a rear face'view of the photographic button shown in Fig. 1.

Fig. 4 is an enlarged section of m improved button taken on line 4-4 of ig. 1.

Fig. 5 is a view similar to Fig. 4 showing the various elements which compose the button in a disassembled relationship, and

Fig. 6 is a greatly enlarged fragmentary section of the sensitized photographic plate.

Referring to the drawings by reference characters I (have indicated my improved photographic button generally at 10. This .photographic button 10 is particularly designed for use in conjunction with my improved coin yactuated automatic photographic camera shown and described in my co-pending U. S.- patent application Serial Number 41,033, filed July 2, 1925, but it may be used in other machines and for other purposes for which it is suitable.

The button 10 is preferably circular as shown and comprises a frame 11, a sensitized photographic plate 12, and a back 14. The photographic plate 12 is provided on one face with a sensitized photographic emulsion 12a' as shown in Fig. 6, and may be provided on its other face with a coating of waterproof material of dark color 12". This coating has many advantages, one is .that it enables the back to be readily ds tinguished from the sensitized face when the button is being assembled.

As shown in the accompanying drawing, the frame l1 1s made from a smgle plece of material and comprises a face port1on 15 .having a central downwardly extendin collar 16 which forms a recess 17, and whic is bent centrally again at substantially right angles to form another planar flange 18 which lies in a plane substantially parallel to the plane of the face portion 15 and which formsl an aperture or sight 19. The outer periphery of the face 15 is bent downwardly to form a collar 20 (see Fig. 5) the lower portion of which in the completed button as shown in Fig. 4, is bent inwardly to form a resilient flange 21 which bears against the back plate 14 and tightly clamps the sensitized photographic plate 12 against the under face of the flange 18. By proportioning the parts as shown and by use of more or less,resilient material the sensitized. photographic plate 12 bears against the under face of the flange 18 and the emulsion is slightly indented and highly compressed to make a fluid tivht joint which will, during the process o? developing and rinsing, prevent fluid from passing into the interior" chamber 22, 4which is formed in the frame 11 by the various elements of the button.

The peripheral edge of the sensitized photographic plate V12 is bent to form a conical flange 23 and the peripheral edge ofthe back plate 14 is similarly bent to form a flange 24. By so forming the peripheral edges of the plate 12 and the back 14 the flange 2l of the frame 11 may abut the back 14 in such a manner that the outer face of the flange 21 does not project into the plane of the back 14, so that no obstruction projects beyond the outer face ofthe back 14. This greatly facilitates stackln the buttons 10 upon one another an formsv a smooth surface upon which the buttons may be moved while in the photographic machine. A

The recess 17 at the top of the .button forms a compartment in which developing fluid is'placed during the developing process and by varying the depth of the recess 17 the quantity of developing fluid used may be varied. f

The various elements which form my improved bntton are preferably made of sheet metal andthe frame which may be of resilient metal provided upon its exposed surfaces with designs or may be left plain as shown in the drawin The frame and the back plate or only t e frame may be plated with nickel, silver, gold or any other substance to appeal to the artistic sense if so desired.

I? desired the 'sensitized plate 12 alone may be used for certain uses. In thisevent .the flange 23 serves to hold the developing and washing fluids.

. From the foregoing description it will be apparent that I have provided an improvedform of photographic button which is simple in construction, durable, and wherein. means is provided for holding a developing fluid during the developing process and wherein means is provided for forming a fluid tight joint ,between the sensitized photographic plate and the frame of the button.

What I claim is: v

1. A button including a frame and a sensitized plate, said plate including a planar bod portion having an upwardly directed peripheral edge, said frame including a top portlon and a bottom portion, said top portion engaging said sensitized plate and means to hold said frame o'n said plate.

2. In a device of the class described, a

lane, round, disc-like sensitized plate havmg ,an integral flange thereon, said flange bemg continuous and arranged at an angle to the plane of the disc to form a cup, the plane portion of said plate having an emulsion thereon.

3. A button including a frame, a sensitized photographic plate and a back, said frame comprisin a continuous front portion engaging said p ate and a rear portion engaging the back of said plate and inlthe same plane therewith, the top of'said frame being disposed above the top of said plate.

4. A button including a'frame, a sensitized photographic late and a back,- said frame being made From a single piece of material, said frame comprising a `face portion, inner and outer cylindrical collars on said face portion and extending at substantially right angles to the face portion, the

inner collar being bent inwardly to form a flange which lies in a plane substantially parallel to the plane of the face portion, said outer collar being bent inwardly to clamp said photographic plate in tight engagementl with said first mentioned inwardly bent L `form inturned front and back flanges,\said front flange being bent to form a flange which engages the said face portion, said -back flange being in clamping feng/agement with said back plate, said back flange being disposed above the plane of the back late. In testimony whereof, I hereunto a X I ny signature.
